Wormholes created by aliens for quick transportation may have already been found, scientists claim

AN advanced alien civilization may have already created wormholes that allow them to travel between galaxies or even universes.

This is according to a few scientists who think we may have even observed wormholes before but lost the evidence in a 'sea of data'.

A very advanced alien civilization may have been able to "manipulate space-time itself to create wormholes", according to a report in BBC .

It notes how Einstein’s theory of gravity allows for these quick routes through space and time to exist.

Scientists aren't sure what a wormhole would look like.

Some have proposed that they could look like black holes and think we could detect them from the energy they emit.

We may have even picked up wormhole data while scanning the universe for other purposes and not realised.

Prof Fumio Abe of Nagoya University in Japan told Science Focus: "If the wormholes have throat radii between 100 and 10 million kilometres, are bound to our Galaxy, and are as common as ordinary stars, detection might be achieved by reanalysing past data."

How does a wormhole work?

In theory, wormholes could act like a magical gateway easily connecting two points in space and time with each other.

In science fiction, they’re often depicted as gateways that can let people step into another time or galaxy.
